6.6
In this LSI, external space areas 2 to 5 can be designated as DRAM space, and DRAM interfacing
performed. The DRAM interface allows DRAM to be directly connected to this LSI. A DRAM
space of 2, 4, or 8 Mbytes can be set by means of bits RMTS2 to RMTS0 in DRAMCR. Burst
operation is also possible, using fast page mode.
6.6.1
Areas 2 to 5 are designated as DRAM space by setting bits RMTS2 to RMTS0 in DRAMCR. The
relation between the settings of bits RMTS2 to RMTS0 and DRAM space is shown in table 6.4.
Possible DRAM space settings are: one area (area 2), two areas (areas 2 and 3), four areas (areas 2
to 5), and continuous area (areas 2 to 5).
Table 6.4
Note:
With continuous DRAM space, RAS2 is valid. The bus specifications (bus width, number of wait
states, etc.) for continuous DRAM space conform to the settings for area 2.
6.6.2
With DRAM space, the row address and column address are multiplexed. In address multiplexing,
the size of the shift of the row address is selected with bits MXC2 to MXC0 in DRAMCR. Table
6.5 shows the relation between the settings of MXC2 to MXC0 and the shift size.
The MXC2 bit should be cleared to 0 when the DRAM interface is used.
